IMPROVEMENT lN COUNTlNG-REGISTERS.

Specification l'orming part of Letters Patent- No.

217,827, dated July 22, 1879; application liled April 23, 1879.

To all whom it may concern:

Be it known that I, EDUARD SirALrmNN, of Buckau, near Magdeburg, in theEmpire of Germany, have invented a new and useful Improvement inEngineltegisters, which improvement is fully set forth in the followingspecification, reference being had to the accompanying drawings, inwhich- Figure 1 represents a plan or top view, the cover of the easehaving been removed to expose the worlting-plate. Fig. 2 is a transversevertical section in the plane 00 00, Fig. 1. Fig. 3 is a longitudinalvertical section in the plane y y, Fig. 1. Fig. at is a transversesection in the plane a .c, Fig. 1. Fig. 5 is a detached elevation of thelatch which serves to lock and release the registering mechanism. Fig.(iis a sectional view of the locking mechanism for the case.

Similar letters indicate corresponding parts.

This invention consists in the combination, in an engine-register, of aseries of drums, which revolve loosely on a common stationary arbor, andeach of which bears on its periphery the figures from 0 to 9; suitablemechanism for transmitting motion from the unitdrum to the ten-drum,from the ten-drum to the hundred-drum, and so on 5 an escapementwheelmounted on or firmly secured to the hub of the unit-drum; ananchor-lever, which carries two pallets adapted to engage alternatelywith the escapeinent-wheel; an opening in the loose end of theanchor-lever; a shaft which connects with the engine or other machinethe motions of which are to be counted, and an eccentric wrist-pinsecured in the inner end of said shaft, and adapted to engage with theopening in the anchor-lever, so that, whenever this shaft receives arevolving or an oscillating motion, each of its revolutions oroscillations causes the escapement-wheel and the unit-drum to advanceone step, and a registcr is obtained which counts the revolutions aswell as the oscillations of an engine or other machine, whatever may bethe direction in which such engine or machine turns. YVith theregistering-drums and the mechanism for transmitting the motion from onedrum to the next is combined a latch, which serves to lock said drums intheir working positions, and

which can be raised so that said drums can be set back to zero.

In the drawings, the letter A designates a case, of metal or any othersuitable material, which incloses the registering mechanism. Thismechanism consists of a series of drums, B B B 13 &c., which are mountedloosely on a stationary arbor, a, resting in standards I) I), which risefrom the bottom of the case A. Each of said drums bears on itscircumference the figures O to 9, and on the hub of the unitdrum B isfirmly secured an escapement-wheel, c, to which a step-by-step movementis imparted by the action of pallets d d, Fig. 2, which are secured toan anchor-lever, (J. This lever has its fulcrum on a pivot, e, which issecured in a standard, j, that rises from the bottom of the case A. Inthe loose end of this lever is formed an opening, {1, preferably oval inform, which embraces an eccentric wristpin, 7L, secured in the inner endof a shaft, D, that is connected to the engine or other machine themotions of which are to be counted.

henever the shaft D receives a revolving or an oscillating motion ofsufficient throw in either direction the pallets of the anchor-lever arecaused to act alternately on the escapement-wheel, causing the same,together with the unit-drum, to turn one step for each completerevolution or oscillation of the shaft 1). By these means the figures 0to 9 on the unit drum are successively brought under an opening, a, Fig.3, in the cover of the case A.

After the unit-drum has been propelled nine steps, and during the timeit completes its tenth step, the ten-drum B is propelled one step by thefollowing mechanism: 011 the edge of the unit-drum which faces theten-drun1 is formed a slightly-depressed rim, j, from which project twoteeth, L, while from the edge of the ten-drum facing the unit-drumproject twenty teeth, Z. These teeth l engage with a small spur-wheel,m, which is mounted loosely on a stationary arbor, a, that is supportedin a standard, 0, Fig. 1, rising from the bottom of the case A. Thespur-wheel in has eight teeth, (see Fig. eh) and on its face is firmlysecured another spur-wheel, p, with four teeth, one of which bears onthe rim j of the unitwheel; but during the time the unit wheel completesits tenth step the teeth k of said unit-wheel engage with the spur-wheelp and impart to the same one-quarter of a revolution, carrying with itthe spur-wheel m, which imparts to the ten-drum one-tenth of arevolution, so that. the figure 10 appears beneath the openings 2' t" inthe cover of the case.

The ten-drum is constructed like the unitdrum, and motion is transmittedfrom it to the hundred-drum by a similar mechanism, and so on from thehundred-drum to the thousand-drum, &c.

The hubs of the adjoining drums are of such a length that they do notpermit the edges of said drums, or the teeth formed on said edges, tocome in contact with each other, and when the several drums are heldclose together and in gear with their spur wheels m 19, only theunit-drum can be turned by hand; but the remaining drums cannot bereturned to zero except by manipulating the unit-drum for a very longtime.

In order to be able to throw the several drums out of gear with theirspur-wheels m 10, I use a latch, E, which swings on the arbor n,

I and is provided with a segmental head, 1", Fig.

5, adapted to catch over the arbor a. This head is of such length thatit fits nicely between the standard b and the hub of the last drum,13*", thereby keeping all the drums close together and in gear withtheir respective spur-wheels m 1); but if the latch E is raised all thedrums are free to slide on the arbor a, and the spur-wheelsm 10 areifree to slide on their'arbor n, so that the drums can be easily thrownout of gear with their spur-wheels and returned to zero in a very shorttime.

It is obvious that the number of teeth in the spur-wheels m p and thenumber of teeth on the edges of the several drums can be changed withoutdeviating from my invention.

What I claim as new, and desire to secure which carries two palletsadapted to engage alternately with the escapement wheel an opening inthe loose end of said anchor-lever; ashaft which connects with theengine or other machine the motions of which are to be counted, and aneccentric wrist-pin secured in the-inner end of said shaft, and adaptedto engage with the opening in the anchor-lever, all constructed andadapted to operate substantially as and for the purpose shown anddescribed.

2. The combination, with a series of registering-drums mounted looselyon an arbor, teeth k 1, formed on the edges of said drums,

spur-wheels m 19, mounted loosely on a second arbor, mechanism forimparting a step-by-step motion to the registering-drums, and a latch,E, for locking the drums in their working position, and for releasingthem when they are to be returned to zero, all constructed and adaptedto operate substantially as set forth.

In testimony that I claim the foregoing I hereunto set my hand and sealthis 3d day of March, 1879.
